B-58 — The Hustler Survivors

Back in the 1950’s, the key factor that the Strategic Air
Command was looking for was speed. Speed was the ability to
deliver an H-bomb anywhere in the Soviet Union in just a
few hours. Speed meant flying so fast that enemy defenses
could not track you, and enemy fighters could not scramble
in time to catch you. Finally, speed meant the ability to
get off the ground ready to deliver a counter-strike in the
event that the enemy launched a preemptive strike.

What SAC had in mind was a Mach 3 bomber that flew at 70,000
feet. This holy grail of bombers, the B-70, would fly higher
than what Soviet missiles could reach, and faster than any
Soviet fighter. But the B-70 would be a long time in coming.
It pushed the edge on just about every system in the aircraft.
It was also very controversial, especially in congress.

The result was a series of interim bombers. The B-36 was seen
as interim until a jet bomber could be deployed. The B-47 was
seen as an interim until a proper heavy bomber came about,
namely, the B-52. Even the B-52 was seen as interim until the
B-70 was ready.

One of these interim projects was a Mach 2 medium bomber.
While the Mach 3 B-70 had to break new ground before it could
be built, a Mach 2 bomber could be built from largely off the
shelf parts. Thus was the genesis of the B-58 project.

The plan called for hauling a single atomic bomb to the heart
of the Soviet Union, and return to a friendly airbase. The power
to do this was available in the GE J79 engine. To haul the bomb,
the plane would need to be about 60 feet wide and 90 feet long.
To move this airframe, (4) of the J79’s would be needed. For
supersonic flight, the wing needed to be delta-shaped. The problem
was that the resulting plane was just too big and fuel hungry to
have the combat range that was needed.

The innovative solution appeared when the plane was broken up
into two parts. The main airplane would house the (3) crew members, engines,
systems, and only the fuel for the return flight. A “mission pod”
was then attached to the underside of the plane. This pod contained
the atomic weapon and the fuel needed for the inbound flight. The
entire mission pod would be dropped when bombing the enemy. This
resulted in a much smaller and lighter airplane for the trip home,
and one that was fully fueled. Add in in-flight refueling to top off
the tanks after take-off, and you now have a 5000 mile combat range.

The B-58 Hustler entered service about 1960, and served 10 years.
A total of 118 planes were built at a program cost of $3-billion.
This meant that each plane was essentially worth more than their
weight in gold. The Hustler did have a number of problems in service,
especially a weak nose gear and a few loss of control crashes, and
it had its share of opponents. In the end, the ICBM took away their
primary mission, and the Hustler could not adapt to low level
penetration flight. They were all but gone by 1970. Only 8 survive
today.
